在appfuse应用架构下用Eclipse进行DAO单元测试

在appfuse应用架构下用Eclipse进行DAO单元测试:
假设工程根目录为%PROJECT_ROOT%
1、把%PROJECT_ROOT%下build\dao\gen等目录加入工程的“Java构建路径”——“库”中的“构建路径上的jar和类文件夹”列表中,完整的须加入的路径:

<classpathentry kind="lib" path="build/dao/gen"/>

<classpathentry kind="lib" path="build/web/classes"/>

<classpathentry kind="lib" path="build/[webappName]"/>

2、为了支持ant test-dao批量单元测试,修改build.xml:
修改<jvmarg value="-Duser.language=cn" />为<jvmarg value="-Duser.language=zh" />
取消db-load任务,<target name="test-dao" depends="copy-resources,package-dao,db-load,check-debug" description="Test dao module">
启用编译单元测试类:
            <!--注销编译单元测试类
            <javac srcdir="test/@{module}" debug="true"
                destdir="${test.dir}/@{module}/classes">
                <classpath>
                    <path refid="@{module}.test.classpath"/>
                    <path location="${build.dir}/@{module}/classes"/>
                </classpath>
                <options/>
            </javac>
            -->
 
 
 

3、为了支持ant test-dao,修改properties.xml的dao.test.classpath,增加

        <fileset dir="${commons.dir}" includes="*.jar"/>

        <fileset dir="${osworkflow.dir}" includes="*.jar"/>

 

测试DAO依赖 mail.properties、database.properties等文件和下列xml文件:
%PROJECT_ROOT%\build\dao\gen\*.hbm.xml
%PROJECT_ROOT%\dao\applicationContext-resources.xml
%PROJECT_ROOT%\build\dao\gen\META-INF\applicationContext-hibernate.xml

下面的代码就可以满足测试DAO的依赖
    protected String[] getConfigLocations() {
        setAutowireMode(AUTOWIRE_BY_NAME);
        return new String [] {"classpath*:/**/dao/applicationContext-*.xml",
                              "classpath*:META-INF/applicationContext-*.xml","/WEB-INF/applicationContext-resources.xml"
};

    }


示例代码如下:

BaseDaoTestCase.java

package com.sunrise.psmis.dao;

import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
import java.util.MissingResourceException;
import java.util.ResourceBundle;

public abstract class BaseDaoTestCase extends AbstractTransactionalDataSourceSpringContextTests {
    protected final Log log = LogFactory.getLog(getClass());
    protected ResourceBundle rb;

    protected String[] getConfigLocations() {
        setAutowireMode(AUTOWIRE_BY_NAME);
        return new String [] {"classpath*:/**/dao/applicationContext-*.xml",
                              "classpath*:META-INF/applicationContext-*.xml","/WEB-INF/applicationContext-resources.xml"}; 
    }
   
    public BaseDaoTestCase() {
        // Since a ResourceBundle is not required for each class, just
        // do a simple check to see if one exists
        String className = this.getClass().getName();

        try {
            rb = ResourceBundle.getBundle(className);
        } catch (MissingResourceException mre) {
            //log.warn("No resource bundle found for: " + className);
        }
    }

    /**
     * Utility method to populate a javabean-style object with values
     * from a Properties file
     * @param obj
     * @return Object populated object
     * @throws Exception
     */
    protected Object populate(Object obj) throws Exception {
        // loop through all the beans methods and set its properties from
        // its .properties file
        Map map = new HashMap();

        for (Enumeration keys = rb.getKeys(); keys.hasMoreElements();) {
            String key = (String) keys.nextElement();
            map.put(key, rb.getString(key));
        }

        BeanUtils.copyProperties(obj, map);

        return obj;
    }
}
